This invention relates to what I na be termed a suction comb and is particu arly adapted for use in the cleamn of cows, horses' and other animals. The evice com '.5 prises a comb which is adapted to sleek the animals coat and at the same time loosen any dirt or scuri which may be imbedded 1n the hair, the suction nozzle, which is comblned with the comb, acting to carry the foreign L matter away immediately and therebyprevent its resettling on the animal.

It will be understood that the suctlon nozzle is adapted to be coupled to any suitable form of vacuum' producing apparatus for i creating the desired suction in the nozzle around the comb.

One object of the invention is to construct the comb in such a manner that loose hair will not become entangled in the comb and thereby clog the nozzle.

Another object of the invention is to form the nozzle in twoseparatc pieces, comprising the nozzle proper and a hollow or tubular handle therefor, and so constructing these elements that the nozzle proper, 'which is of wide expanse and is adapted for use in cleaning the readily accessible parts of the animal, may be quickly removed from the hollow handle which on its end is provided with comb teeth and is adapted to be used alone in cleaning those parts of the animal which are not so readily accessible.

Referring to the drawings:

Fig. 1 is a longitudinal sectional elevation of ,the device taken on the line 1-1, Fig. 2;

Fig. 2 is a transverse sectional elevation taken on the line 2 2, Fig. 1;

Fig. 3 is an inverted plan view;

Fig. 4 is an end view of the tubular handle of the device; and

Figs. 5, 6, 7 and 8 illustrate alternate forms of the invention. p

The device comprises a suction nozzle 1, which consists of an elongated substantially flat hollow body portion 2 which gradually increases in height from its opposite ends toward its center where the said hollow body portion is provided with a substantially cylindrical hollow extension 3, which projects from one side of the said body portion at an angle with respect to the general plane of the saidbody portion. e respective side walls 4 and 5 ofthe hollow body portion 1 are spaced apart to forman elongated mouth oropening 6 in which is located the comb 7. j

The comb 7 comprises a`solid portion or back Swhich is located within the opening 6 of the body portion 2 and is spaced above and substantially parallel to the bottom edge 9 of thev said body portion12. Teeth 10 of the comb project from the back 8 of the comb to a point below or outside the bottom edge 910i1 the body portion 2 of the suction nozz e The comb 7 may be applied to the nozzle by slotting the end walls 11, 11 of the body portion 2 as at 12 and placing the ends of the comb in said slots, swaging the ends of the comb over the said end walls 11 at each side of the slots, or by sweating, soldering, or welding the comb in the slots, or by locating the comb in a suitable die and casting the body portion 2 around the comb to hold vthe comb in place.

The metal at the base of spaces formed between adjacent teeth is beveled in both direct-ions from the central plane of the comb as indicated at 13 presenting a knife edge to the jdirt and hair being drawn into the nozz e li have found by experimentation that this construction prevents loose hairs from piling up between the teeth and clogging the nozzle, the knife edge 14 preventing the hairs from balancingon Ithe comb with one end on oney side thereof and the other end on the opposite side thereof, such as happens when the base of the spaces between the teeth are permitted to remain flat and at right angles to the direction of travel of the air moving into the nozzle.

Obviously for 'short haired animals the teeth 10 do not extend as far below the bottom edge 9 lof the nozzle as is Vthe case wherethe comb is to be used on long haired animals. Likewise the spacing of the teeth may vary in accordance with the state of compactness of the hair on different animals.

'By m king` the T c'ombsjf removablafcombs is slightly' tapered to receive the externally tapered end 15 of a suitable hollow handle pgrts of the animal the nozzle 1 is employed,l

ing frictionally held on the hollow handle 16 but for the places less accessible, such for example as the places where the limbs join the body, the nozzle 1 may be removed and the toothed end of the hollow handle emplo ed to comb and clean in such places,in whlch case the hollow handle functions as the nozzle. j

Placing the comb directly in the center-,of

the nozzle mouth or opening 6 and running the comb longitudinally of the opening with the walls 4 and 5 spaced relatively close to the comb on each side thereof permits the dirt to be loosened by the comb and immediately removed from the hair and does not allow the ,dirt to settle on another part ofthe animals bod Spacing the knife edges 14 inwardly from the bottom edge 9 of the nozzle permits the teeth to thoroughly comb the hair without the hair becoming entangledin the teeth by the suction in the nozzle. If desired, the comb may be removably se cured in the nozzle 1 in any suitable manner,

suchfor example as that illustrated in Fig.A

5, wherein the ends of the lcomb 7a extend beyond the end walls 11, 11 as illustrated at 18, and a pin or other.y securing device 19 passed through the ends 18 ofthe combs resting in socketsl 20 form'edat` the intersection of the bead 21, whichfs formed -around the .rions existent conditions.

' mouthy of the lnozzl'e,j vcithj-the body portion having various degrees oflcoursenessgorteeth of various lengths, etc.,may-bereadilyplaced in the nozzle tomeet the requirements of -va-y In Fig. 6, I have shown a comb 7b in which the teeth are curved outwardly, ina direction away from the handle of the nozzle, as illustrated at 10b, the ortion of the teeth extending beyond the p ane w-w of the mouth of the nozzle being disposed substantially at an.

angle relative to the plane of ther mouth of the nozzle. This curvature of the teeth obviates the possibilities of the teeth pressing into the hide when the device is pushed-rather `than pulled over the hide. In pushing .the device over the hide,the curvature-of thev teeth 10b presents the lower portion of the teeth at an acute anglel withrespect'ftothe' h1de whereupon the teeth will readily ride maaien over the hide rather than having a tendency to dig into the hide. In pulling the device over the hide the natural tendency is for the teeth to move away from the hide, therefore, there is vno tendency for the teeth to dig into the hide. The operation of this form of the '1 device is smooth and` eicient even in the hands 'of the most inexperienced or` indiscreet'operator. v 't Obvlously the curvature of the teeth 10b may ,be eliminated vand the portion of the teeth extending beyond the plane wof the mouth yof the nozzle bent at an angle other than ninety degrees with res ect to said plane as shown at 10c Fig. 7, wit equal eifectiveness.

In Figs. v7 and 8, I have shown a comb adapted especially for use with animals which are shedding hair. In this form of the invention the teeth of. the comb are spaced relatively far a art andthe bases of the aces between t e teeth are curved as at 20, t ereby presentin no shar corners in which loose hair may co lect. A so these bases are beveled on one side only as indicated at 130, and these bases are located but a slight distance from the glane :v -w of the mouth of the nozzle, so t atv should any loose hairs become entangled'in the teeth of the comb they may be readily removed by merely removing the nozzle 1 from the handle 16 and vrunning the end .of the handle across the comb, the suction in the handle 16 thereby removing the loose hairs from the teeth of the comb. l
